Every webmaster should do link building to get a better SERP for Google results. They should build one way links for targeted anchor text. There are lots of free link building methods. Few of them are,
1. Forum Posting( Use do-follow forums and use your URL & anchor text as signature)
2. Blog commenting (Use do-follow blogs)

6. Link exchange with other related sites.
All above link building methods have their advanatages. But here I will be discussing about Forum link building.
